Abstract: The transmission line is an integrated system consisting of conductor subsystem, ground wire subsystem and one subsystem for each category of the support structure. Mechanical supports of transmission line represent a significant portion of the cost of the line and they play an important role in the reliable power transmission. They are designed and constructed in the wide variety of shapes, types, sizes, configurations, and materials. In general, most towers may be idealized as statically determinate and analyzed for wind forces as per IS 875 part 3:1987. Revised code IS 875 is introduced in 2015. In revised code IS 875: Part 3-2015, loading and design parameters are changed. In this paper, the comparison of code IS 875: Part 2-1987 and EN 1991-1-4:2005 will be carried out.
